Irwin IRWIN® HSS Titanium Metal Drill Bit Set, 13 Piece IW3038503

IRWIN® HSS Pro Titanium 13 Piece Drill Bits are designed for drilling metal and harder alloys, as well as being able to produce increased drill speeds of 40-60% in comparison to the standard bits. With a titanium nitride coating, the drill bits offer higher friction resistance and longer life. Their 135° split point ensures perfect centring and minimises bit walk, while also reducing drilling pressure, giving a more accurate and clean finish. Heavy-duty web construction is designed to optimise strength and durability of the drill bits. Supplied in a handy storage case. Specifications: Sizes: 1.5, 2, 2.5, 3, 3.2, 3.5, 4, 4.5, 5, 5.5, 6, 6.5 and 7mm.
